I think this is a good idea to create balanced information. IF the platform has reached a certain size, ie...Facebook, Twitter etc. The problem is that with their overreaching bias, they are wrongfully influencing normies with their disinformation campaigns to affect national sentiment.

The precedent here is: back when railroad barons ruled the west, many towns popped up that were on the railroad corporations property. These barons weren't always very fair in their dealings with employees and the public. Inevitably the people that lived in these towns became very vocal about mistreatment. Whereupon, the corporation booted and banned them from their towns.

A court ruling on the case determined that once a town reached a certain size, even though it was owned by a corporation, was at that point considered public domain. And that constitutional rights, such as freedom of speech, could not be abrogated. The parallel here with Twitter is very similar.
